Edited to add: If the link takes you to a big roundabout with 'Hoad Way' on it, that's wrong, but just scroll to the south west and the roundabout I'm talking about is the one nearest to Theale railway station.

Just to be clear, it's the roundabout between Daly International and Sungard and you're travelling roughly in a southerly direction staying on Station Rd.

You might be better off screen grabbing google maps as Station Road is not the link you have said.

You have linked Bath Road passing through Hoad Way and Waterside Drive.

Really? Jees, sorry. The image upload doesn't work from work, so I'll have to re-post tonight - sorry again. This is worth pursing as this has been bugging me for years. The actual roundabout is due SW of the one you mentioned; just north of Theale station.

Assuming I'm supposed to be travelling from under the flyover and trying to get to the bridge over the railway, then the left lane. I use this road occasionally; use the left lane and have never had a problem.

I would stick to left hand lane, to avoid cars entering from Brunel Road trying to sneak to my inside. I would not indicate at the Brunel road entrance, until cars from Brunel Rd could no longer see my front left indicator, or I was alongside them. Even then, only if there were road users behind or approaching the roundabout going north on Station Rd that would benefit from a signal (also for the benefit of pedestrians, cyclists or electric buggies that may be waiting to cross at this last exit).

Thanks for your replies. I deliberately kept the original post neutral, but I'll now reveal why this was a mystery to me. Virtually every car I see on this roundabout is going straight on and using the right hand lane to do so. There are rarely queues when I take it, but often one car going straight on. It gives me an awkward conundrum, because obviously if I'm in the left lane (as per the Highway Code), we'll come together on the exit.

I thought the Highway Code was quite clear that from a single carriageway to another single carriageway, the left lane is for all exits up to and including 12 o'clock. Could anyone who vote for the RHL give their reasoning? Something is causing Jo Public to use the right lane exclusively for going straight on and avoid the left hand lane. I can't see any evidence of arrows on the road, and there's no sign giving lanes either.

This may seem like a small point, but I've been taking this roundabout once a week for years now and it always confuses me why other drivers do what they do on it.
